Stone blocks

Stone is produced from rock rubble via a Stonecutter's table after it is researched. To create stone right click the table, click 'Bills', and use the + and - buttons to set how many pieces of rubble you wish to consume. You must have a colonist with 'crafting' enabled in the Overview menu. Stone blocks are always produced in batches of 20 per rock chunk. Stone can also be obtained by deconstructing abandoned structures that are randomly scattered throughout the map, though these must be Claimed first.

Cut stone can be used to supplement other valuable resources, namely steel and wood. It can be used to craft walls (even the conduit walls that carry electricity), or fancy floors with faster than default walk speed and less mood penalty. Cut stone can be used to craft everything from doors, automatic doors, tables, benches, to beds and royal beds. It is also the prime resource for crafting sculptures for colonists with the Artist skill.

While doors made of stone are very hard for enemies to destroy, they also take a long time to open, so consider making the Autodoor variant to save time. It also doesn't give nearly as much rest effectiveness as wooden beds do.

Stone walls and structures appear to take 3 times as much damage from explosive weapons (like Mortars) as structures made of other materials.

Granite blocks

Blocks of solid granite. Granite is a very hard stone.

Granite is the strongest of all stone blocks and is best suited to build walls in the fighting area.

Marble blocks

Blocks of solid marble. Marble is a soft, beautiful stone, known for being easy to sculpt.

Of all stone block materials, marble has the highest Beauty factor and stands alone as the sole stone to have a beauty bonus, and so is the best stone block to create art for your base. It is also a close second in terms of market value per unit of work, after sandstone, so is well suited to craft items for sale in bulk.

Sandstone blocks

Blocks of solid sandstone. Sandstone is a relatively soft rock and chips easily.

Sandstone is the quickest stone type to work with, making it well suited for stone constructions that need to be built quickly. It also has the highest market value per unit of work so is the best stone type for crafting items for sale in bulk.
